“I saw the people standing here and I looked up and I was sitting in Starbucks and I went ‘Oh,’”

Officials aren’t sure what caused the separation. “No idea. These are buildings. It happens. Specific cause, we’ll probably never know. A lot of vibrations (go) through here, traffic, 100-year-old buildings, it could be anything,” Wassick said.

Autumn Clark has an office in the building. “It didn’t even look like there was any damage in that office,” she told News 8 after being allowed inside to look around.

The building also houses the State Theater. According to a post on its Facebook page, the theater is delaying the start of its concert Sunday night by an hour, citing parking concerns.

P&G Masonry Restorations will perform the repair work on the facade. The company said crews are waiting for a crane to arrive so workers can inspect it more closely to ensure its stability. That crane is not expected to arrive until Monday.

As a result, High Street from Congress Street to Deering Street will remain closed.

“For people’s morning commute, they will probably want to seek an alternate route, especially those folks who come across the Casco Bay Bridge,” Portland City Spokesperson Nicole Clegg said.
